I'm not sure about that METAR. They are reporting the pressure in both conventional and old methods. It looks to match up apart from the 0600 GMT METAR which converting the old method would give 995hPa. Also at that time I make the centre 65km to the WNW based on the advisory so I think the 995hPa value is more likely. Also I see the pressure at Subic Bay has not dropped below 989hPa up to 0800 GMT.
